Application August 13', 1938, Serial No. 224,782-

3 Claims.

The deviceforming the subject matter of this application is adapted to be mounted in the fuel line of an internal combustion engine, to the end that the, fuel may be broken up and vaporized. One object of the invention is to supply an article .of the class described which may be adapted With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. 1 is a longitudinal section on the line l-| of Fig. 3, parts remaining in elevation;

. Fig. 2 is a longitudinal section in a plane at right angles to the cutting plane in Fig. 1;

Fig. 3 is a section on the line 33 of Fig. 1;

Fig. 4 is a section on the line 4-4 of Fig. 2.

The device forming the subject matter of this application is adapted to be used anywhere in the fuel line of an internal combustion engine. In Figs. 1 and 2, the numeral I designates conduit members having outstanding flanges 2. A gasket 3 isinterposed between the flanges 2, and the flanges 2 are clamped on the gasket 3 by securing elements 4. The end of the conduit |l which is disposed toward the carburetor is marked by the numeral 5, and the end which is disposed toward the intake manifold is marked by the numeral 6.

The article forming the basis of the present application preferably is made of metal throughout. It comprises curved side walls 20, which are spaced apart, circinnfe'rentially, at their longitudinal edges, as shown at 2|. The side walls 20 have, each, an outwardly extended flange 22.

The side walls 2|] are bendable throughout their entire width, and they are bendable, also, at

places 23 where they are joined, integrally, to the .outer edges of radial, plate-like fins l1. Owing to the construction last above referred to, the side walls 20 may be so shaped, by bending, as to conform to the bore 21 of any fuel conduit, and 5 it is not necessary to provide a plurality of devices" of the class de'scribed, in order to fit fuel conduits of different internal diameters, an observation which will beappreciated readilywhen Fig. 4 of the drawing is noted. 1

- The radial, plate-like fins I! have tapered, curved-ended tips l8, whichhave a circumfer entia'l inclination. The tips; are supplied with any desired number of perforations l9. At their inner ends, the fins I! have curved arms 50, 15

provided with outstanding radial fingers 5!. The finger'5l on the arm 56 of each fin I? is attached to the next adjoining fin I! by securing elements 52. The curved arms 50 cooperate to; form a tubular socket 53.

In the socket 53 is located a tubular axial bearing 7, comprising a body 54 and a foot ring 8. Thebody 54 has a reduced end, threaded into the foot ring 8. Through the foot ring 8, through the reduced end of the body 54 and through the 25 socket 53 is extended a securing element lit, which may be a rivet. The bearing 1 has a doublediametered bore defining a shoulder. In the body 54 of the bearing 1, a shaft is journaled, the shaft including a main member I0 having a reduced end H, the parts Ill and II defining a shoulder H which cooperates with the shoulder of the bearing I to prevent the shaft I0H from moving endwise in one direction. Endwise movement of the shaft IDH in an opposite direction is prevented, and the shaft is anti-frictionally supported for rotation, by a single ball 9 which is interposed between the end of the main member 10 of the shaft l8-ll and the securing element 6%. 4

A rotor is provided, and includes any desired number of blades l4, two oppositely disposed blades being shown, although the invention is not limited to the use of two blades. The blades l-l have a suitable pitch, as indicated in the drawfairly good size, and being located adjacent to the outer ends of the blades.

It is to be observed that the device has no continuous base, constructed in general outline like the flanges 2 of the conduit members. The securing devices 4 do not pass through any portion of the structure forming the subject matter of this application, the flanges 22 simply being bound between the gasket 3 and one of the flanges 2, as shown in Fig. 1. The gasket 3 is the ordinary gasket used in making a tight joint in the fuel conduit, and no other or additional gaskets are required. The flanges 22 are seated in the standard gasket 3, as shown in Fig. 2, when the securing elements 4 are tightened up.

The operation of the structure so far as breaking up the fuel and vaporizing it are concerned, will be understood readily from the drawing. The article may be turned out, as to the walls 20, the fins H and the flanges 22, in a single operation.

The device shown produces a snappy engine operation, a saving of fuel, a quick pick-up, increased power, a minimum carbon monoxide production, and there will be little carbon accumulation.

Having thus described the invention, what 1s claimed is:

1. A gas mixer of the class described, including a central bearing, substantially radial mixing fins, means for securing the inner ends of the fins to the bearing, and circumferentially extended walls each joined along one edge to the outer edge of one of the fins, the opposite edges of the walls being free throughout their entire length, the walls being bendable throughout their entire width to different curvatures, thereby to adapt the mixer to fuel conduits of different diameters, transversely-spaced means carried by the walls and movable relatively to each other when the walls are bent as aforesaid, for anchoring the mixer in a fuel conduit.

2. A gas mixer of the class described, including a central bearing, substantial radial mixing fins, means for securing the inner ends of the fins to the bearing, and circumferentially extended walls each joined along one edge to the outer edge of one of the fins, the opposite edges of the walls being free throughout their entire length, the walls being bendable throughout their entire width to different curvatures, thereby to adapt one mixer to fuel conduits of difierent diameters, the walls having transversely spaced outwardly extended anchoring flanges movable relatively to each other when the walls are bent as aforesaid, for holding the mixer in a fuel conduit.

3. A gas mixer of the class described including a socket having substantially radial mixing fins and circumferentially extended walls each joined along one edge to the outer edge of one of the fins, the opposite edges of the walls being free, the walls being bendable to different curvatures, thereby to adapt one mixer to fuel conduits of different diameters, means for anchoring the mixer in a fuel conduit, a bearing in the socket, the bearing comprising a body and a foot ring detachably connected thereto, a securing element connecting the body and the foot ring of the bearing and mounted in the socket, a spinner including a shaft journaled in the body of the bearing, and a single ball interposed between one end of the shaft and the securing element.
